LettersA Patent No. 82,027, dated September 8, 1868.

IMPROVBMNT IN REGIPROCATING lSfliAllfl*ENGINES 'T0 ALL WHOIVI IT MAY CONCERN:

Be it known that I, Jessen B. PEDnIcLoflLow'ell Mills, in the county of Bartholomew, in,the Stute of indiana, have invented a new and improved Device for Controlling and' Reversing Steam-Engines; mid I do hereby declare that the followingl is afuill 'and exact description thereof, reference being had to the'ccor'panying drawings, and to the letters of reference mai-kerl thereon.

The nature of my invention consists4 in providing evolve-bex., or co'lhliiristion of'boires, :isV shown in Figure 1, perspective, and marked G und M.

v M is e valve-box containinga valve, K, tl1`e" "1 1se` of which isto make the pipes BA and D Cfeed .and

exhaust-pipes alternately to and from the cylinders, for a better understanding of which reference is had to the Y vertical sectional View, Figure 2, inwhich H is the -pipe connecting with the boiler, sind I is the escape-pipo'.

Figure 3 is a valve. The bottom, o r portion that rests uponthc seat, is show'n, and markefd Y; This is the same valve shown in the valve-box M, and marked K, iig. 2, and is double, that is, it has two openings through it, one of whichvconnects with the -ppes B and A, andthe other-with the pipes D and This valve s worked bythe lever, and when the lever is thrown forward or towards the'valveLboit M, the' steam will pass through the valve'K, and into the pipe D, g.2; thence into the valve-box E N, and above the plste'P; thence through the plate and vai?A into .he cylinder-,from which it exhausts into the box N; thence,V

to the pipe B, thence to the box M, thence through the pipe I.

When theflever 0 is thrown backward, or from the valve-box, the steam will pass in to tlic pippe B; thexicet A into the box E N;thence into the cylinder, from which it will exhaust. through the valve L; thence through the pipe D into the box M; thence through the pipe I.

If the lever' is brought to a perpendicular, the valve K will shut th'e steam all-0E from the` cylinders. The farther' the lever O is moved fromva. perpendicular, the more steam it will admit, und thenearer it approaches a perpendicular, the less it will admit to 'the engine, thereby giving complete controloverthe same. Whent is desired to run b oth engines in the same direction at the same time, and'in opposite directions at other times, the double valve K should be made in two parts, as shown in Figure 4, each part to be worked by a lever in the usual manner. ,i n Y The valves are all so constructed as t'o admitof packing betweenl them and their respective plates. What I claim, and desire to secure by Letters Patent, is- A The arrangement of the valve K, vlvc-boxes G M, and the pipesB A. and C D, substantially as shown and described. i
